Slang term for a Formic, an insect-like alien race from the book Ender's Game by Orson Scott Card. Formics were often called buggers because they resembled ants to some degree, and a hive-like reporductive strategy.

Noun: A gadget, usually in the form of a plug or socket, inserted into an electronic device in order to test or bypass interlocks. Also used to make the damn thing work because the interlock has failed at a critical time. USA Navy slang, WWII vintage, now much used in the USA National Labs.

Verb: To bypass an interlock, either directly with a jumper, or by the use of a "bugger".
